南京某明挖地铁车站的中庭结构设计方法分析

以南京第一座明挖大空间中庭式地铁车站为例，分析影响中庭结构设计方法的关键问题，即在中庭开洞范围内，剩余中板与中柱形成的结构体系对侧墙的约束效果和中柱在产生侧向位移时的结构安全及稳定性，提出可供同类工程设计参考的方法和措施。

Analysis on Design of Atrium Structure of a Metro Station in Nanjing Constructed by Cut and Cover Method

Taking the first large space atrium Metro station in Nanjing, which is constructed by cut and cover method, as an example, the authors analyze the key factors that influence the design of the atrium structure, including the restriction effect of the structure composed by the remaining intermediate floor slabs and the intermediate columns on the side walls and the structural safety and stability of the intermediate columns under lateral displacement conditions. Furthermore, the authors also propose methods and measures that can be used as references for the design of similar projects in the future.
